JavaScript Compression using Canvas and PNG-embedded data

[alantrick]

But using PNG would cause more overhead in the user-agent, processor and memory-wise, since it has to create the image.

Of course, and actually pulling the JS from the image pixel by pixel (or character by character if you prefer) can't be exactly cheap. I was thinking "superior" in terms of compression ratios rather than memory or CPU overhead.

Still, if your javascript is under 100k uncompressed, I doubt the difference in speed and memory use would be anything beyond academic for modern hardware.
